Helical Milling in NX9.0

I am having trouble with creating a helical milling cycle to machine a non round shape in NX9. No problems with a cylindrical bore or boss.

If it is not round then your not cutting a helix. 

 

Can you post an image of what you want to cut?

I don't know if you mean an actual machine "cycle" - I have not seen one.

 

Round holes and bosses have hole_milling and boss_milling operations in the hole_making type.

 

To do a general helical pattern on a closed shape, I would look at surface contouring with either streamline or surface area drive method. If the drive geometry forms a closed loop, then the "Helical or Spiral" cut pattern is available.

I have tried Streamline contouring with drive setting set to helical, but not having any luck.

I managed to get it to work with Streamline by setting the projection vector. Thanks for the help..

Good to see you got it going.

Another option is Zlevel with ramp between levels, and a small ramp angle. You can get a continuous path, and also G3 moves in the corners.
